Used only once. The condition is very good, but upon inspection for listing, I found stains on the lunch box belt and bag. Photos 4 and 12. I didn't notice the stain on the bag unless I looked closely. This is similar to the one Takizawa Makiko-san introduced before. Please refrain from purchasing if you are seeking perfection. The insulated bag will be folded for shipping. Sports day Lunch box Square three-tier lunch box
